Welcome to HelioClim
This server is an on-going effort of Ecole des Mines de Paris/Armines, Center for Energy and Processes, to provide information on solar radiation. It is a companion to the SoDa Service.
The item Education is available in English and French. It comprises a series of lectures on the climatology of the radiation over Europe. Also available are applets Java for the course of the sun in the sky. Units and Terminology are dealt with.
The Heliosat method converts Meteosat satellite images into data maps of solar radiation. The method calls upon libraries describing the solar geometry, the satellite geometry and clear-skies models. These libraries are freely available as sources in C as well as the method Heliosat.
The calibration of Meteosat images is an important element for the exploitation of large time-series of images.
By the means of the methods Heliosat, the databases HelioClim of solar radiation (irradiation or irradiance), were, and are, created by processing Meteosat images. These databases run since 1985. They can be accessed through the SoDa service. The SoDa service delivers information on solar radiation (data, databases, algorithms, advanced applications).
Values of Linke turbidity factor can be accessed through the SoDa Web service. The database of the Linke turbidity factor is available for the whole world.
Other services, previouly offered by the HelioClim server, such as simulations of the clear-sky irradiation, simulation of system for hot water production, PAR computation...) are now part of the service SoDa.
ESRA (European Solar Radiation Atlas) is an atlas made on behalf of the European Commission (Brussels, Belgium). The CD-ROM and the PC-software for its exploitation are commercially available through Les Presses de l'Ecole des Mines de Paris. An overview of the atlas is given here, with an emphasis on maps.
A service is available for the control of the quality of measurements of global irradiation. Enter your own series of data and check their plausibility.
Other servers exist whose main goals support the HelioClim initiative. Links are given to these servers.
